Does this happen also in a TStringGrid which is the descendant of TValueListEditor?

Tried it myself: Yes, TStringGrid has the same issue.

Attaching a test program to see the issue with TValueListEditor and TStringGrid.

Is caused because the grid title is drawn after the cells. As a consequence the grid.Canvas.Font is that of the title when a cell is prepared for editing. Added a line to reset the Canvas.Font to that of the grid before the editor size is calculated.

Please test and close if ok.

ValueListEditor does not seem to be working correctly between the Titefont and font for the grid.

the size of the cell for the title is the size of the grid cell when ever you change the grid.font.size but the font size for the title remains to that of the Title setting font..

basically, it's messed up the other way, too..

so what to do ?

 Checking older versions of Laz, it appears this behavior has been there so maybe this can be addressed at some other time as to the font.size in the grid making changes to the title cell size too.

Do you want the height of the title row to change along with the TitleFont.Size? This would be a feature request - the current report is about a bug. And I am not sure whether this should be implemented at all because there may be other criteria to determine the title row height conflicting with such an automatism. And it's a one-liner, after all, to adjust the title row height after an update of the TitleFont.Size.
